Optical and Near-IR Observations of the Faint and Fast 2008ha-like Supernova 2010ae
M. D. Stritzinger, E. Hsiao, S. Valenti +21
A comprehensive set of optical and near-infrared (NIR) photometry and spectroscopy is presented for the faint and fast 2008ha-like supernova (SN) 2010ae. Contingent on the adopted…
Persistent C II Absorption in the Normal Type Ia Supernova 2002fk
Régis Cartier, Mario Hamuy, Giuliano Pignata +16
We present well-sampled photometry of SN 2002fk starting 12 days before maximum light through 122 days after peak brightness, along with a series of 15 optical spectra f…
Multi-Epoch High-Spectral-Resolution Observations of Neutral Sodium in 14 Type Ia Supernovae
A. Sternberg, A. Gal Yam, J. D. Simon +16
One of the main questions concerning Type Ia supernovae is the nature of the binary companion of the exploding white dwarf. A major discriminant between different suggested models…
On Discovering Electromagnetic Emission from Neutron Star Mergers: The Early Years of Two Gravitational Wave Detectors
Mansi M. Kasliwal, Samaya Nissanke
We present the first simulation addressing the prospects of finding an electromagnetic (EM) counterpart to gravitational wave detections (GW) during the early years of only two adv…
A Tidal Flare Candidate in Abell 1795
W. P. Maksym, M. P. Ulmer, M. C. Eracleous +2
As part of our ongoing archival X-ray survey of galaxy clusters for tidal flares, we present evidence of an X-ray transient source within 1 arcmin of the core of Abell 1795. The ex…
Discovery and redshift of an optical afterglow in 71 square degrees: iPTF13bxl and GRB 130702A
Leo P. Singer, S. Bradley Cenko, Mansi M. Kasliwal +20
We report the discovery of the optical afterglow of the gamma-ray burst (GRB) 130702A, identified upon searching 71 square degrees surrounding the Fermi Gamma-ray Burst Monitor (GB…
